The display portion 28 includes a display unit such as a display device.The display portion 28 is supplied with a display instruction signalfrom the control portion 22 and displays various display screens basedon the supplied display instruction signal. In this case, the controlportion 22 can allow the display portion 28 to display various screenssuch as a home screen H as shown in FIG. 2A and an operation inputrestriction screen R as shown in FIG. 2B.

The home screen H is provided with operation buttons Ba through Bf foroperating contents A through F. The above-mentioned interoperationapplication can perform the contents based on interoperation between thevehicular communication apparatus 2 and the mobile telephone 3. Thoughnot shown, the home screen H can be provided with an operation buttonfor operating an application other than the interoperation application,that is, an application except contents A through F the interoperationapplication can perform. Any application other than the interoperationapplication can be configured in accordance with specifications of themobile telephone 3, for example.

The operation input restriction screen R is provided with adisconnection button Bg and a home button Bh. The disconnection buttonBg frees or disconnects a short range communication line establishedbetween the vehicular communication apparatus 2 and the mobile telephone3. The home button Bh changes the operation input restriction screen Rto the home screen H. An area of the operation input restriction screenR except the disconnection button Bg and the home button Bh disables thetouch operation and might be dimmed, for example.

The home screen H is displayed when the mobile telephone 3 operates innormal mode. Alternatively, the home screen H is displayed when the homebutton Bh is pressed on the operation input restriction screen R that isdisplayed on the mobile telephone 3 in operation restriction mode. Thenormal mode is enabled for the mobile telephone 3 that is notcommunicably connected to the vehicular communication apparatus 2. Thenormal mode enables unlimited ordinary operations of an applicationinstalled in the mobile telephone 3. The mobile telephone 3 canindependently perform contents A through F included in theinteroperation application when the mobile telephone is not communicablyconnected to the vehicular communication apparatus 2.

The microphone 29 inputs the voice uttered from a user as transmissionvoice. When the telephone communication portion 23 a receives the voicefrom an intended party, the speaker 30 outputs the voice as receptionvoice. The power supply portion 31 supplies the power discharged from abattery 32 as operating power to respective function blocks. The battery32 is attachable to and detachable from the mobile telephone body.

As described above, the USB communication line is connected between theUSB modules 6 and 25 and the BT communication line is connected betweenthe BT modules 5 and 24. In this state, the mobile telephone 3 as acommunication party of the vehicular communication apparatus 2 uses theUSB communication line and the BT communication line as multipleresources for transmitting various types of data to the vehicularcommunication apparatus 2. In this case, the mobile telephone 3 receivesa command from the vehicular communication apparatus 2 that requests themobile telephone 3 to start outputting various types of data. The mobiletelephone 3 then uses any one of the USB communication line and the BTcommunication line as resources to transmit various types of data to thevehicular communication apparatus 2.

The communication line establishment portion 41 uses the BT module 24 toperform a process that establishes the BT communication line as awireless short range communication line to the BT module 5 of thevehicular communication apparatus 2. The communication lineestablishment portion 41 uses the USB module 25 to perform a processthat establishes the USB communication line as a wired short rangecommunication line to the USB module 6 of the vehicular communicationapparatus 2.

When connected to each other through the communication line, thevehicular communication apparatus 2 and the mobile telephone 3 implementthe interoperation function. This function allows the vehicularcommunication apparatus 2 and the mobile telephone 3 to interoperatewith each other while each of them performs the interoperationapplication installed as the specific application. For example, anapplication performed on the vehicular communication apparatus 2 can beoutput from the display portion 28 or the speaker 30 of the mobiletelephone 3. By contrast, an application performed on the mobiletelephone 3 can be output from the display device 19 or the speakers 17a and 17 b of the vehicular communication apparatus 2.

The interoperation detection portion 42 detects that an interoperationstate is established while the vehicular communication apparatus 2 andthe mobile telephone 3 interoperate with each other. The interoperationstate ensures interoperation between the interoperation applicationstored in the vehicular storage portion 7 of the vehicular communicationapparatus 2 and the interoperation application stored in the mobilestorage portion 26 of the mobile telephone 3.

The interoperation detection portion 42 detects that an interoperationstate is established as described above. After that, the operation inputdisable portion 43 inhibits or restricts the mobile operation inputportion 27 of the mobile telephone 3 as to operations for theinteroperation function of the interoperation application.

The operation input enable portion 44 releases an operation inputdisable state in which the operation input disable portion 43 inhibitsthe mobile operation input portion 27 of the mobile telephone 3 fromoperating the interoperation function of the interoperation application.Specifically, as shown in FIG. 2B, the operation input enable portion 44displays the disconnection button Bg so as to be operable on the screenof the display portion 28 when the BT or USB communication line isestablished between the vehicular communication apparatus 2 and themobile telephone 3 to enable the connection capable of short rangecommunication therebetween. Operating the disconnection button Bgdisconnects the connection using SPP, for example, one of profilesestablished between the vehicular communication apparatus 2 and themobile telephone 3. This releases the operation input disable stateactivated between the vehicular communication apparatus 2 and the mobiletelephone 3.

With reference to FIG. 3, the following describes operations of theabove-mentioned configuration. FIG. 3 shows operations of the mobiletelephone 3 in the BT communication system 1. The following describesthe restriction on operations of the mobile telephone 3 that caninteroperate with the vehicular communication apparatus.

The control portion 22 of the mobile telephone 3 monitors whether themobile telephone 3 is connected to the vehicular communication apparatus2 so as to be capable of short range communication. That is, the controlportion 22 monitors whether the interoperation state is established toenable interoperation between the interoperation application stored inthe vehicular storage portion 7 of the vehicular communication apparatus2 and the interoperation application stored in the mobile storageportion 26 of the mobile telephone 3 (step S1). In this case, thecontrol portion 22 determines that the mobile telephone is connected tothe vehicular communication apparatus 2 so as to be capable of shortrange communication via the BT communication line under the conditionthat the SPP connection is established.

The profile SPP can indicate a communication correspondent apparatuswhen the connection is established. Based on the SPP, one apparatus,i.e., the mobile telephone 3 issues a connection request. In response tothe request, the other apparatus as a communication correspondentapparatus, i.e., the vehicular communication apparatus 2 configures avirtual serial port. The vehicular communication apparatus 2 notifiesinformation indicating itself to the mobile telephone 3 as an origin ofthe connection request. The information is referred to as communicationcorrespondent information equivalent to a signal “spp (vehicularcommunication apparatus 2),” for example. The control portion 22 of themobile telephone 3 is notified of the communication correspondentinformation. Based on this information, the control portion 22 confirmsthat the communication correspondent apparatus is equivalent to thevehicular communication apparatus 2. The control portion 22 establishesSPP connection with the communication correspondent apparatus. Based onthe communication correspondent information in the SPP, the mobiletelephone 3 can determine whether the vehicular communication apparatus2 functions as a communication correspondent apparatus for the BTcommunication when the BT communication line is established between themobile telephone 3 and the vehicular communication apparatus 2.According to the embodiment, the control portion 22 of the mobiletelephone uses the SPP function and determines whether the SPPconnection is established and accordingly determines whether the mobiletelephone 3 is communicably connected to the vehicular communicationapparatus 2.

Concerning the USB communication line, there may be a case where the USBconnection cable 14 is physically connected to the USB module 25 or thevehicular communication apparatus 2 as a connection party is detectedvia the USB connection cable, for example. Under such a condition, thecontrol portion 22 can determine that the mobile telephone 3 isconnected to the vehicular communication apparatus 2 through the USBcommunication line so as to be capable of the short range communication.

The BT or USB communication line is established between the vehicularcommunication apparatus 2 and the mobile telephone 3 when the mobiletelephone 3 is communicably connected to the vehicular communicationapparatus 2. The interoperation state may be established to enableinteroperation between the interoperation application stored in thevehicular storage portion 7 of the vehicular communication apparatus 2and the interoperation application stored in the mobile storage portion26 of the mobile telephone 3 (YES at step S1). In this case, the controlportion 22 changes the mobile telephone 3 to the operation restrictionmode (step S2). In the operation restriction mode, as described above,the mobile telephone 3 displays the operation input restriction screen Rthat allows operations of the disconnection button Bg and the homebutton Bh only. The control portion 22 comes to be inoperable andrestricts all the contents A through F the interoperation applicationshould be able to perform.

After the mobile telephone changes to the operation restriction mode,the control portion 22 monitors whether the disconnection button Bg ispressed on the operation input restriction screen R (step S3). Thecontrol portion 22 monitors whether the home button Bh is pressed on theoperation input restriction screen R (step S4).

When the disconnection button Bg is operated (YES at step S3), thecontrol portion 22 releases the connection state capable of the shortrange communication with the vehicular communication apparatus 2. Thatis, the control portion 22 especially disconnects the SPP short rangecommunication line established between the mobile telephone 3 and thevehicular communication apparatus 2 (step S5). The control portion 22changes the mobile telephone 3 to the normal mode (step S6). The mobiletelephone 3 displays the home screen H. The mobile telephone 3 is readyto operate all the contents A through F the interoperation applicationshould be able to perform.

The home button Bh may be operated in the operation restriction mode (NOat step S3 and YES at step S4). In this case, the control portion 22changes the operation input restriction screen R to the home screen H(step S7). The mobile telephone 3 is ready to operate applications thatare performed on the vehicular communication apparatus 2 and are notassociated with the contents A through F the interoperation applicationcan perform. In this case, the home screen H may be preferably displayeddifferently from the normal mode. For example, the operation buttons Bathrough Bf shown in FIG. 2A may be dimmed and disabled for operationsbecause these buttons are associated with the contents A through F andare targeted for the operation restriction. Though not shown, there maybe an operable button that is associated with the other applications andis therefore activated.

According to the embodiment, as described above, the vehicularcommunication apparatus 2 mounted on a vehicle allows the vehicularstorage portion 7 to store the interoperation application thatimplements the interoperation function. The vehicular operation inputportion 10 enables operations for the interoperation function of theinteroperation application. The mobile telephone 3 is communicablyconnected to the vehicular communication apparatus 2. The mobiletelephone 3 allows the mobile storage portion 26 to store theinteroperation application that implements the interoperation function.The mobile operation input portion 27 enables operations for theinteroperation function of the interoperation application. The mobiletelephone allows the interoperation detection portion 42 to detect thatthe interoperation state is established. The interoperation stateenables interoperation between the interoperation application stored inthe vehicular storage portion 7 of the vehicular communication apparatus2 and the interoperation application stored in the mobile storageportion 26 of the mobile telephone 3. The mobile telephone then allowsthe operation input disable portion 43 to inhibit operations for theinteroperation function from the mobile operation input portion 27 ofthe mobile telephone 3.

The vehicular communication apparatus 2 and the mobile telephone 3 arecommunicably connected to each other to establish the interoperationstate that allows interoperation between the interoperation applicationstored in the vehicular communication apparatus 2 and the interoperationapplication stored in the mobile telephone 3. Establishing theinteroperation state restricts or inhibits the mobile telephone 3 fromentering operations for the interoperation function the interoperationapplication implements. It is possible to ensure safe interoperationbetween the application performed in the vehicular communicationapparatus 2 and the application performed in the mobile telephone 3communicably connected to the vehicular communication apparatus 2.

According to the embodiment, the control portion 22 of the mobiletelephone 3 can allow the operation input enable portion 44 to releasethe operation input disable state that inhibits the mobile operationinput portion 27 from entering an operation for the interoperationfunction.

The operation input disable state inhibits the mobile telephone 3 fromentering operations for the interoperation function the interoperationapplication implements. A user can release the operation input disablestate as needed using the disconnection button Bg displayed on theoperation input enable portion 44. While the vehicle stops, for example,the user can release the operation input disable state and operate theinteroperation application from the mobile telephone 3.

When the operation input enable portion 44 releases the operation inputdisable state, the mobile telephone 3 may release the interoperationstate that enables interoperation between a specific application storedin the vehicular storage portion 7 of the vehicular communicationapparatus 2 and a specific application stored in the mobile storageportion 26 of the mobile telephone 3. Subsequently, the mobile telephone3 itself may allow the mobile operation input portion 27 of the mobiletelephone 3 to enable operations for the specific application stored inthe mobile storage portion 26 of the mobile telephone 3.

The operation input disable state is released for the purpose ofimproving the usability and eliminating excessively restrictive use sothat the mobile telephone 3 is ready for operation only when the usercan safely operate the mobile telephone 3 while the vehicle stops, forexample. Releasing the operation input disable state is not intended toallow the use of the mobile telephone 3 when the user needs toconcentrate on the driving while the vehicle is running.

Even in the operation input disable state, pressing the home button Bh(YES at step S4) allows the control portion 22 of the mobile telephone 3according to the embodiment to perform an application other than theinteroperation application.

According to the embodiment, only the interoperation application can bedefined as a specific application that needs to be prevented againstoperations. Applications other than the specific application need not beprevented against operations. The mobile telephone 3 can enteroperations for these applications without restriction regardless ofwhether a communication line is established. That is, the mobiletelephone 3 can be allowed to enter operations for only minimalapplications.

As described in the embodiment, the vehicular communication apparatus 2and the mobile telephone 3 are communicably connected to each other inaccordance with multiple profiles. The mobile telephone 3 allows theoperation input enable portion 44 to disconnect the connection based onSPP, a specific one of the profiles, and release the operation inputdisable state.

According to the embodiment, the SPP communication standard can indicatea communication correspondent apparatus when the connection isestablished. Using SPP, the control portion 22 of the mobile telephone 3allows the communication line establishment portion 41 to establish acommunication line with the vehicular communication apparatus 2. Whenthe communication line is established for the vehicular communicationapparatus 2, the control portion 22 of the mobile telephone 3 uses SPPto confirm that the communication correspondent apparatus corresponds tothe vehicular communication apparatus 2. The control portion 22 thenallows the operation input disable portion 43 to restrict entry ofoperations for the interoperation function of the interoperationapplication.

The mobile telephone 3 may communicate with a communicationcorrespondent apparatus equal to the vehicular communication apparatus2. In this case, the mobile telephone 3 can be inhibited from operatinga specific application performed on the vehicular communicationapparatus 2. The mobile telephone 3 may communicate with a communicationcorrespondent apparatus such as a navigation system different from thevehicular communication apparatus 2. In this case, the mobile telephone3 can operate a specific application performed on the apparatus. Thatis, the mobile telephone 3 can be inhibited from operating the specificapplication performed on the vehicular communication apparatus 2 whenthe mobile telephone is connected to the vehicular communicationapparatus 2 as the communication correspondent apparatus so as to becapable of short range communication.

It is possible to ensure safe interoperationbetween the application performed in the vehicular communicationapparatus and the application performed in the portable terminalapparatus communicably connected to the vehicular communicationapparatus.

Alternatively, the portable terminal apparatus may further include: anoperation input enable device that releases an operation input disablestate activated by the operation input disable device. In the operationinput disable state, the operation input disable device prevents themobile input device from entering the operation for the predeterminedfunction. In this case, the operation input enable device can releasethe operation input disable state that prevents the portable terminalapparatus from entering an operation for the predetermined functionimplemented by the specific application. While the vehicle stops, forexample, a user can release the operation input disable state.

Further, when the operation input enable device releases the operationinput disable state, the portable terminal apparatus may release theinteroperation state that allows interoperation between thepredetermined vehicular application and the predetermined mobileapplication. The mobile input device enables entry of an operation forthe predetermined mobile application.

Alternatively, the portable terminal apparatus may allow an operation ofan application other than the predetermined mobile application in anoperation input disable state. In the operation input disable state, theoperation input disable device prevents the mobile input device fromentering the operation for the predetermined function. In this case, thespecific application may be defined as only an application that requiresrestriction on operation input. The portable terminal apparatus canensure unlimited entry of operations for an application other than thespecific application, that is, an application that requires norestriction on operation input. That is, the portable terminal apparatuscan be allowed to enter operations for only minimal applications.

Further, the vehicular communication apparatus and the portable terminalapparatus may be communicably connected to each other in accordance witha plurality of communication standards. The operation input enabledevice releases the operation input disable state by disconnectingconnection in accordance with a predetermined one of the communicationstandards.

Alternatively, the portable terminal apparatus may be communicablyconnected to the vehicular communication apparatus in accordance with acommunication standard, which provides to indicate a communicationcorrespondent apparatus when connection is established. The operationinput disable device prevents the mobile input device from entering theoperation for the predetermined function after the operation inputdisable device confirms in accordance with the communication standardthat the communication correspondent apparatus for the portable terminalapparatus is the vehicular communication apparatus. The portableterminal apparatus may communicate with a communication correspondentapparatus equal to the vehicular communication apparatus. In this case,the portable terminal apparatus can be inhibited from operating aspecific application performed on the portable terminal apparatus. Theportable terminal apparatus may communicate with a communicationcorrespondent apparatus different from the vehicular communicationapparatus. In this case, the portable terminal apparatus can operate aspecific application performed on the apparatus. That is, the portableterminal apparatus can be inhibited from operating the specificapplication when the portable terminal apparatus is communicablyconnected to the vehicular communication apparatus as the communicationcorrespondent apparatus.

Alternatively, when the interoperation detection device detects theestablishment of the interoperation state, the vehicular input devicemay enter the operation for the predetermined function so that thepredetermined function is executed.

Alternatively, the portable terminal apparatus may further include: aselection device for selecting one of the interoperation state andrelease of the interoperation state. When the selection device selectsthe release of the interoperation state, the portable terminal apparatusreleases an operation input disable state activated by the operationinput disable device. In the operation input disable state, theoperation input disable device prevents the mobile input device fromentering the operation for the predetermined function.

Alternatively, when the operation input enable device releases anoperation input disable state, the mobile input device may enter theoperation for the predetermined function so that the predeterminefunction is executed.
